rReplacing Color Wheel

The NP4100/NP4100W projector comes with a four-segment color wheel installed. An additional six-segment color wheel comes included. To replace the color wheel (located under the lamp cover adjacent to lamp 1) refer to the following guide.

Note:

•Before replacing the color wheel, be sure to turn off the projector, wait until the cooling fans stop, and turn off the main power switch.

•Wait until the lamp house and the color wheel cool off.

•Do not touch the disk of the color wheel. Doing so may scratch the disk or leave fingerprints, causing the image quality to degrade.

•Heed the following information if you own two or more NP4100/NP4100W projectors:

When replacing or re-installing the color wheel, the original color wheel pre- installed or supplied as an accessory must go back to its original projector. Your color wheel and projector color wheel cover are given an identification number. Be sure to use the color wheel pre-installed or supplied with your projector to match its identification number.

If you remove a color wheel from one NP4100/NP4100W projector and re-install it into another NP4100/NP4100W projector, performance may be compromised.

•Be sure turn off the main power switch before replacing the color wheel. Failure to do so may result in electrical shock or damage to the projector, and cause an ir- regular color of the projected image.
